SCREEN R STORM-SASI-I FASTENER.

Specification of Letters Patent.

Patented Mar. 23, 1920.

Application filed April 21, 1919, Serial No. 291,487. Renewed February 5, 1920. Serial No. 356,422.

To all whom it may concern Be it known that we, FRANK BANG, Jr., and WILLIAM E. CHRIsrLE, citizens of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improve ments in Screen or Storm-Sash Fasteners; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to screen and storm sash for windows, more particularly storm sash, and the object of the invention is to provide a simple, cheap, secure and easily operated device for fastening the storm-sash, both in its closed and open positions.

The nature of the invention is fully disclosed in the description and claims following, reference being bad to the accompanying drawings, in which Figure 1 is a fragmentary side elevation of a window, partly in section, showing the application of our improved fastener thereto Fig. 2 is a sectional plan view of the same, showing the storm sash closed, and the fastener in its proper position. Fig. 3 shows the fastener bar detached. Fig. 4 shows a modification in the construction of the same.

in the drawing, the numeral 5 denotes a storm sash, supposed to be pivotally hung at the top (not shown.) in a familiar way. It is the usual practice to provide the bottom rail of the sash with a hook and eye 6. and in the window sill 7 to attach a screw eye 8 at the proper distance for hooking the sash tightly closed. Our device is designed to hold the sash open a limited distance, for the admission of air, and is described as follows:

A. bar 9, of slightly flexible steel, preferably, is provided near one end with a hole 10 to receive the screw-eve 8. The opposite end of the bar is bent to form an offset 11 to receive the inner, lower angle of the sash, as shown in Fig. 1. A little distance inwardly from the offset is an eye 12, which registers with the hook when the bar is in its sashholding position. In practice the hook should engage the eye rather tightly, which the slight flexibility of the bar permits it to do by bending the bar upwardly a little. This forces the offset snugly into contact with the bottom rail of the sash, andso prevents any possible rattle or vibration of the sash in the wind. When it is desired to close the sash the hook is disengaged from the eye of the fastening bar, the bar is folded back on the sill, as shown in Fig. 9., and the hook is engaged with the screw-eye 8.

Instead of an attached eye 12, suitably secured to a fiat bar, as by riveting, the eye may be a simple hole 12 in the bar itself, which for convenience of engagement of the hook is twisted, as shown in Fig. 4.

Having thus described our invention, we claim:

1. A storm-sash fastener, comprising a hook attached to the sash, an engaging member attached to the window sill, and a bar having an offset at its outer end to engage the lower, inside angle of the sash, an eye to engage said hook, and means to attach said bar pivotally to the window sill.

2. A storm-sash fastener. comprising in combination, a hook attached to the sash, a screw-eye to engage said hook, attached to the windowsill. a bar secured at one end by said screw eye, and having an offset at its outer end to engage the lower. inner angle of the sash. and provided with an eye to ensaid hook and at a proper distance from. the. ofi'set to hold it snugly against the sash when open,

3. A storm-sash fastener, comprising a hook attached to the sash, an eye for the same attached to the window-sill. and a slightlv flexible bar nivotallv secured to the window-sill b said eve, its outer end offset to engage the lower, inner angle of the sash, and an eve spaced away therefrom to engage the hook tightly by springing the bar up slightly.

In testimony whereof we aflix our signatures in presence of two witnesses.
